Abstract: A barcode-reading device can send barcode images to a remote server for decoding. A decoder on the remote server can process the images and attempt to decode any barcodes in the images. Once the decoder on the remote server has successfully decoded a barcode, the remote server can send the decoded data back to the barcode-reading device and/or to a host computing device that is communicatively coupled to the barcode-reading device. If the barcode-reading device receives the decoded data, the barcode-reading device can forward the decoded data to the host computing device. In some embodiments, a barcode-reading device can send all captured images to the remote server. Alternatively, a barcode-reading device can send only some captured images to the remote server. In some embodiments, a barcode-reading device can be configured to perform one or more preliminary processing operations on an image before sending the image to the remote server.

Abstract: The disclosure concerns systems and methods for controlling access to a device with barcode-reading functionality. Enabling the barcode-reading functionality of the device may require providing authenticating information. A user may provide the authenticating information using an identification card with an embedded near field communication (NFC) tag. After the device or a charger of the device validates the embedded NFC tag, the device may enable the barcode-reading functionality but track an amount of time since a last barcode scan of the device. If the amount of time since the last barcode scan reaches a present period, the device may disable the barcode-reading functionality. The device may send a connection request from a portion of a local area network (LAN). A server may receive the request. The server may deny the device access to the LAN if the device is not authorized for use in the portion of the LAN.
